How to cancel Belfius by mail
Find your account details
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Belfius is the easiest one to set aside.
Write your request
State plainly that you want the Belfius account cancelled, further charges stopped and a written confirmation sent to you. Postbye sets this out in a ready English template (“Subject: Subscription termination – Belfius”).
Post the letter
Take the letter to the post office and ask for certified delivery to 1210 Brussel. Keep the tracking number it gives you.
Keep the proof of delivery
It shows the date Belfius received your letter. Check your next statement: no Belfius charge should post after the cancellation date.

Before you cancel Belfius, check these
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works

If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
